Abstract
The invention relates to a novel sliding-end universal joint, which has a swing angle being up to 30 degrees. Mounting angles of a fixed-end universal joint and the sliding-end universal joint can be allocated reasonably, and the sliding-end universal joint can work on a condition of being away from the maximum swing angle of the sliding-end universal joint, so that the difference between the service life of the universal joint at the fixed end and the service life of sliding-end universal joint can be reduced. The novel sliding-end universal joint comprises a shell, a retainer, a star-shaped bush and steel balls. The star-shaped bush is provided with eight, twelve or sixteen outer races, each outer race consists of an outer race with an inclined angle of gamma=0 degree and an outer race with an inclined angle of gamma=16 degrees, the outer races with the inclined angle of gamma=0 degrees and the outer aces with the inclined angle of gamma=16 degrees are distributed at intervals uniformly, and each two adjacent outer races with the inclined angle of gamma=16 degrees are distributed in a symmetrical manner relative to the outer race with the inclined angle of gamma=0 degree between the two adjacent outer races. Besides, the shell is provided with inner races correspondingly, the inner races match with the outer races of the star-shaped bush, the number of the steel balls is equal to that of the outer races, and the steel balls are mounted between the shell and the star-shaped bush by the aid of the retainer.
Description
Technical field
The present invention relates to a kind of universal joint, relate in particular to a kind of novel slippage end universal joint.
Background technique
Automobile-used constant velocity universal joint is divided into fixed end universal joint and slippage end universal joint substantially.Wherein slippage end universal joint is divided into three big series again: curved grooved type (Weiss) constant velocity universal joint, the flexible constant velocity universal joint of Rzeppa type (Rzeppa), the pivoting constant velocity universal joint that stretches that stretch.Max=20 ° of the flexible constant velocity universal joint pivot angle β of curved grooved type; The flexible constant velocity universal joint of Rzeppa type is divided into DO joint and VL joint, max=22 ° of their maximum pendulum angle β again; And the flexible constant velocity universal joint of pivoting is divided into TJ type and GI type, maximum pendulum angle β max≤20 °.
Rzeppa universal joint comprises shell, retainer, star sleeve, steel ball, and this retainer, star sleeve, steel ball are installed in the enclosure, and assembling back star sleeve slides in the enclosure freely and is limited in the enclosure.Shell is fixed on the output terminal of differential mechanism through bolt during use; Through the spline tooth structure, star sleeve is connected with semiaxis.At present, the fixed end constant velocity universal joint that automobile is used is about about 120,000 kilometers general working life, and the slippage end is about about 270,000 kilometers.Wherein go-anywhere vehicle and beach buggy generally need be raised the chassis of automobile, deacclimatize those rugged road conditions, and Cardan shaft will need a very big established angle like this.In general, the pivot angle of slippage end all smaller (less than 22 °), thus it is more to require on such car the fixed end universal joint to share the setting angle ratio.Because of having increased the established angle of fixed end universal joint, the operating mode degree-of-difficulty factor of fixed end universal joint increases, and then can descend relatively working life; Correspondingly slippage end constant velocity universal joint established angle also can increase, and also can reduce its working life; And the gap increase in working life of fixed end universal joint and slippage end universal joint, promptly go-anywhere vehicle and beach buggy fixed end are about about 90,000 kilometers, and the slippage end is about about 260,000 kilometers.Provide the universal energy-conservation reasonable distribution established angle of the big slippage end of a kind of pivot angle to make under the operating mode of fixed end universal joint away from its maximum pendulum angle and work, thereby the gap that reduces the working life of slippage end universal joint and fixed end universal joint is the technical problem that the technician needs to be resolved hurrily.
Summary of the invention
In order to overcome disadvantages of background technology, the present invention provides a kind of maximum pendulum angle to reach 30 ° novel slippage end universal joint.
The technological scheme that the present invention adopts is: a kind of novel slippage end universal joint; Comprise shell, retainer, star sleeve, steel ball; On said star sleeve, be provided with raceway outside 8,12 or 16; Said outer raceway is made up of the outer raceway of the outer raceway of γ=0 ° and γ=16 °, and the outer raceway of the outer raceway of said γ=16 ° and said γ=0 ° is uniformly distributed with form at interval, the outer raceway of every adjacent two γ=16 ° be with at it between the two the outer raceway of γ=0 ° be symmetrical distribution; On said shell, correspondingly be provided with interior raceway; Raceway is made up of the interior raceway of the interior raceway of γ=16 ° and γ=0 ° in said; The interior raceway of the interior raceway of said γ=16 ° and said γ=0 ° is uniformly distributed with form at interval; The interior raceway of every adjacent two γ=16 ° be with at it between the two the interior raceway of γ=0 ° be symmetrically distributed and assembling after to be used for installing the bearing of trend of interior its two raceway of raceway of outer raceway and γ=16 ° of γ=16 ° of same steel ball corresponding; The quantity of steel ball is consistent with the quantity of said outer raceway, and said steel ball is installed between said shell and the said star sleeve through retainer.
On the basis of such scheme and as the preferred version of such scheme: comprise also being used for forming the double ender that is in transmission connection that said double ender and said shell are one-piece type to be become with the speed changer output terminal.
On the basis of such scheme and as the preferred version of such scheme: on said double ender, be positioned at and be used for installing the needle bearing place and be provided with spiral appearance oil groove.
The present invention compared with prior art its beneficial effect is: the pivot angle of the novel slippage end of the present invention universal joint can reach 30 °; In assembling, can share more setting angles; Thereby make under the operating mode of fixed end universal joint away from its limit pivot angle, reach the purpose of the gap in the working life that reduces slippage end universal joint and fixed end universal joint.
